I am on the same system, with the same
problem, and I solved it as follows...

>From my literate configuration file:

Copy the =$PATH=, =$MANPATH=, and =LC_ALL=
variables from the interactive login shell to
Emacs.  This is necessary on macOS, as its
GUI starts programs within a minimal
environment.

In practice, this fixes various problems,
such as the =*compilation*= buffer not
finding =emacs=, =fortune= not finding
=strfile=, =geiser-mode= not finding =guile=,
=emacs= not finding =gcc= for native
compilation, as well as, spurious =locale=
warnings.

#+BEGIN_SRC emacs-lisp :eval no :tangle ~/.emacs
(when (eq window-system 'ns)
  (defun shell-get-environment-variable+ (variable)
    "Return the value of VARIABLE from login shell."
    (shell-command-to-string
     (format "$SHELL --login -c 'echo -n $%s'" variable)))
  ;;
  ;; Set the path variable.
  (let* ((path "PATH")
         (path-value (shell-get-environment-variable+ path)))
    (setenv path path-value)
    (setq exec-path (split-string path-value path-separator)))
  ;;
  ;; Set the locale.
  (let* ((variable "LC_ALL")
         (variable-value (shell-get-environment-variable+ variable)))
    (setenv variable variable-value)))
#+END_SRC

P.S. 1: My code launches the login shell
twice instead of once, which is something to
improve.

P.S. 2: It would be useful to have a command
that does this in vanilla Emacs.
